public interface StelaForceModel

This interface represents a force modifying spacecraft motion for a StelaGTOPropagator.

Objects implementing this interface are intended to be added to a semianalytical Stela GTO propagator before the propagation is started.

Parameters:

orbit - current orbit information: date, kinematics

Returns:

the partial derivatives of the current force

Throws:

OrekitException - if partial derivatives computation fails

getType

String getType()

Returns:

the type
